I'm after a proper induction kit for the 3.0 TDI quattro, either a full kit by a performance manufacturer or if someone has done a homemade job with some silicone pipe, filter and jubilee clips etc, I'd love to hear from you and how you did it. Or if you found that one for the 3.0, 3.2 or 4.2 petrols worked just as well.  A search online has revealed nothing for me sadly, no support for the diesels, only some petrols. I know diesels don't rely on air as much as the petrols, maybe this is why I'm struggling to find one that fits. If nothing comes of this and no one can help, I'm tempted to have a go at making one myself and will post some 'how to' pics below. Thanks in advance! Josh 

Personally i'd stick with standard airbox with performance filter.I had an increased diameter intake pipe, wagner intercooler,some other subtle mods and remapped 320bhp.A bloke on another forum makes the larger intakes.Can be seen below if you zoom in.

Excuse me being blunt Huw, but why on earth are you replying to a 7 year old post!?
